AbstractDiversity of freshwater fishes from Son Tra Peninsula, Da Nang City is provided for the first time. Intensive field survey and laboratory analysis have revealed 16 species, belonging to 14 families of 10 orders of freshwater and brackish water fishes. Those fishes are distributed in two different areas like upper stream and from lower stream to the seashore habitats. Most of the species were collected at elevation below 100 meter above sea level. In 16 mentioned species, marbled eel is evaluated at Vulnerable level according to Vietnam Red Data Book (2007) while mosquito fish and tilapia are listed as invasive species in Vietnam. The diversity of fishes species is relatively low in comparison with other protected areas might be due to the small area and isolation of water bodies as well as steep topography.

AbstractToday, wind energy sources are increasingly attracting researchers as well as companies that exploit and use wind energy because of great benefits from this energy source, especially for environmental benefits. However, in order to effectively exploit and use wind energy, one of the important areas is forecasting. It is essential to accurately forecast wind speed and power output of wind farms. The information provided by the forecast not only serves the calculating and generating power of the plant itself, but also serves the operator of the grid where the wind power plant is connected. This paper presents a forecasting methodology considering spatial and temporal correlations. The proposed approach is suitable for simultaneously forecasting correlated wind speed of multiple wind power plants.

AbstractRitual speech plays an inportant role in teaching Russian as a foreign language. Ritual speech – “speech formulas” – “available language units”, if used incorrectly, will lead to the disability of communication. This article presents the basic issues on ritual speeches including: general conception of ritual speech; socio – linguistics with ritual speech; stylistics with ritual speech; situation semantics with ritual speech; national linguistics with ritual speech and dialogue document with ritual speech. The society imposes ritual conduct/behavior (including verbal behavior) whenever it establishes and maintains the contact with interlocutor and requires native speakers to follow this rule. In addition, ritual speech is closely related to rhetoric, situation, semantics and national linguistics.
